Abstract

This study analyzed the utilization status of the blue swimming crab (BSC), (Portunus pelagicus) in Kebumen coastal waters. Field research was conducted from October to December 2024. Biological characteristics related to growth and infinity carapace width (CW∞) were assessed, along with mortality and exploitation rates. Results showed a carapace width (CW) at 50% capture (CWc 50%) of 11.95 cm and an infinity carapace width of 18.38 cm. Peak BSC recruitment occurred in May. An exploitation rate of 0.31 indicates that the BSC population in Kebumen coastal waters is currently underexploited.
